Stackpole Announces UL 1412 Qualified SP3A Fusible Wirewounds



Stackpole has achieved "UL Recognized Component" status for its 4 watt axial leaded fusible wirewound SP3A Series through qualification to UL1412 (File # E344795). This series has a welded element which combines the outstanding surge handling characteristics associated with wirewound resistors, with the failsafe operation required by UL1412. This UL spec is created to ensure that electronic components do not pose a fire or electrical shock hazard. Stackpole's proprietary fusible resistor design yields a reliable and repeatable fusing characteristic so that the part fails quickly, safely, and without generating excess heat This type of component is ideal for protection of monitors, TV's and displays, as well as appliances. This component is also well suited for HVAC monitoring and control systems, safety and security systems, and other commercial and industrial power and control applications. These applications typically require robust continuous power and pulse power handling in a circuit protection resistor. The SP3A adds to Stackpole's growing product offering of agency approved resistors. The RWT and SPR series are UL and CSA qualified. This allows design engineers to accelerate their products through the UL qualification process and shorten their time to market. The SP3A Series is available in tape and reel packaging in 500 piece quantities. Pricing for the SP3A in full reel quantities ranges from $0.18 to $0.25 each.
